                                <h3>题目描述</h3><p><p>给你一个由A，G，T,C组成的字符串，其实就是基因串.<br />
大家知道基因串是AGTCAGTCAGTC这样的形式。现在对这个<br />
字符串进行位置编号，从0开始，到N-1，N代表整个字符串<br />
的长度。现在给出T个要求，希望你对给出的字符串进行一些<br />
变动，变动的方式有三种<br />
1:设置某个位置的字符不可变<br />
2:将某个位置的字符上升一个，例如从C变成A<br />
3：将某个位置的字符下降一个，例如T变成G<br />
注意两个相邻位置的字符不能同时发生变动<br />
对于这T个要求，它们分别会给出一些位置，要求从这些位置取出来的<br />
字符形成一个回文串。<br />
</p></p><hr/><h3>输入格式</h3><p><p>第一行给出N，T （1&lt;=N&lt;=100000,1&lt;=T&lt;=6000)<br />
接下来有T行，每行先给出一个长度L，再给出L个数字其值在[0,N-1]</p></p><hr/><h3>输出格式</h3><p><p>输出&quot;YES&quot;或者&quot;NO&quot;</p></p><hr/><h3>样例输入</h3><pre>5 3
